Measurement of the differential dijet production cross section in proton-proton collisions at \sqrt{s} = 7 tev

TL;DR

This paper reports a measurement of the double-differential inclusive dijet production cross section in proton-proton collisions at 7 TeV, covering a wide mass and rapidity range, and finds good agreement with QCD predictions.

Contribution

First measurement of dijet cross sections at 7 TeV across a broad mass and rapidity range using CMS data, validating QCD models.

Findings

Good agreement with next-to-leading-order QCD predictions.

Dijet mass range from 0.2 TeV to 3.5 TeV.

Jet rapidities up to |y|=2.5.

Abstract

A measurement of the double-differential inclusive dijet production cross section in proton-proton collisions at \sqrt{s}= 7 TeV is presented as a function of the dijet invariant mass and jet rapidity. The data correspond to an integrated luminosity of 36 pb^{-1}, recorded with the CMS detector at the LHC in 2010. The measurement covers the dijet mass range 0.2 TeV to 3.5 TeV and jet rapidities up to |y|=2.5. It is found to be in good agreement with next-to-leading-order QCD predictions.
